Abstract
A method, apparatus and program product utilize pressurized fluid flow from a position generally upstream of a free end of a packaging material tail and at an acute angle relative to the side of a load while the free end of the packaging material tail is unsupported and/or utilize pressurized fluid flow in two or more directions and from two or more positions to assist in adhering a packaging material tail to the side of a load at the completion of a wrapping operation.
Claims43
A method of securing a packaging material tail to a side of a wrapped load, the packaging material tail formed by severing a web of packaging material extending between a corner of the load and a cutting assembly, the method comprising:
- directing a first flow of fluid towards the packaging material tail at a first angle relative to the side of the load;
- and
- directing a second flow of fluid towards the packaging material tail at a second angle relative to the side of the load;
- wherein the first angle is smaller than the second angle;
- and
- wherein directing the first flow of fluid towards the packaging material tail is performed while a length of the packaging material tail extending from the corner of the load to a free end thereof is unsupported.
A method of securing a packaging material tail to a side of a wrapped load, the method comprising:
- severing a web of packaging material extending between a corner of the load and a cutting assembly to form a packaging material tail extending from the corner of the load;
- directing a first flow of fluid towards the packaging material tail from a first position generally upstream of a free end of the packaging material tail and at a first angle relative to the side of the load while a length of the packaging material tail extending from the corner of the load to the free end of the packaging material tail is unsupported to cause the packaging material tail to come into contact with the side of the load;
- and
- after directing the first flow of fluid towards the packaging material tail, directing a second flow of fluid towards the packaging material tail from a second position and at a second angle relative to the side of the load to increase adherence of the packaging material tail to the side of the load;
- wherein the first angle is an acute angle relative to the side of the load and the second angle is substantially orthogonal relative to the side of the load.
A method of securing a packaging material tail to a side of a wrapped load, the method comprising:
- severing a web of packaging material extending between a corner of the load and a cutting assembly to form a packaging material tail extending from the corner of the load;
- and
- with a flow device, directing a flow of fluid towards the packaging material tail from a position generally upstream of a free end of the packaging material tail and at an acute angle relative to the side of the load while a length of the packaging material tail extending from the corner of the load to the free end of the packaging material tail is unsupported to cause the packaging material tail to come into contact with the side of the load, wherein at least a portion of the flow device is supported by a support assembly that is at least partially inside of a zone of rotation for a packaging material dispenser to move between a storage position and an operating position.
